Abstract
Due to the heavy increase of the use of computer networks for both commercial and academic use, network-based applications are nowadays a topic of major interest. Adding video and audio to computer applications and their use in computer networks has specific requirements on the quality issue. In the area of computer-based and distributed applications we are confronted with a large variety of distribution applications we are confronted with a large variety of distribution channels and output devices with different characteristics regarding bandwidth, processing power, display size, etc. The goal of AVWoD project - Audio-Video-Web-on-Demand - carried out at Fraunhofer IGD is to develop the concepts and to build the base for distributed, integrational multimedia applications. AVWoD is a distributed, network-based system which enables the integrated and synchronized transmission and presentation of audio, video, and WWW hypertext documents. Users can select avilable sessions which are prov ided by a AVWoD server. A session in the AVWoD context consists of synchronized media data streams sharing a common topic. The system is based on the use or adaption of HTTP, RTP and UDP/IP as communication protocols, MBone tools in the area of audio and video presentation and Java for user interface design. In the first part of this paper we will describe and discuss the different requirements and the following realizations of the AVWoD system. In the following realizations of the AVWoD system. In the following sections the different parts of AVWoD will be explained and discussed in detail. Of main importance is the quality issue, which leads to concepts of media scalability. Conclusions and prospects are given at the end of the paper.
